How to use the Cost Savings Payback Calculator
Use the extra cash costs and savings relative to keeping the current setup. Enter recurring maintenance separately to avoid treating gross savings as net savings.
The calculation
Worked example
$3,000 upfront and $150 net monthly savings give a twenty-month simple payback.
Assumptions and limits
Constant cash flow; no financing, discounting, residual value or changing energy prices. Non-positive net savings gives no finite payback under this model.
